Mysql 安装文档总结

Mysql 安装文档总结
1.下载
[root@hadoop001 ~]# cd /usr/local
[root@ hadoop001 local]# wget https://downloads.mariadb.com/archives/mysql-5.6/mysql-5.6.30-linux-glibc2.5-x86_64.tar.gz

2.检查是否安装MySQL
[root@ hadoop001 local]# ps -ef|grep mysqld
root 2493 2423 0 19:48 pts/3 00:00:00 grep mysqld
[root@ hadoop001 local]# rpm -qa |grep -i mysql

3.解压压缩包
[root@ hadoop001 local]# tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@ hadoop001 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql

4.创建组和用户
[root@ hadoop001 local]# groupadd -g 101 dba
[root@ hadoop001 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@ hadoop001 local]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
[root@ hadoop001 local]# passwd mysqladmin
Changing password for user mysqladmin.
New UNIX password:
BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@ hadoop001 local]#

*## if user mysqladmin is existing,please execute the following command of usermod.
##[root@ hadoop001 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin #

## copy 环境变量配置文件至mysqladmin用户的home目录中,为了以下步骤配置个人环境变量*
[root@ hadoop001 local]# cp /etc/skel/.* /usr/local/mysql ###important
cp: omitting directory /etc/skel/.'
cp: omitting directory/etc/skel/..’
cp: omitting directory `/etc/skel/.mozilla’

5.Create /etc/my.cnf(640)
#defualt start: /etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf->$MYSQL_HOME/my.cnf-> –defaults-extra-file->~/my.cnf
[root@ hadoop001 mysql]# cd /etc/

6.chown and chmod privileges and try first install

8.Configure mysql service and boot auto start
[root@hado hadoop001 ~]# cd /usr/local/mysql
#将服务文件拷贝到init.d下，并重命名为mysql
[root@hado hadoop001 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql
#赋予可执行权限
[root@ hadoop001 mysql]# chmod +x /etc/rc.d/init.d/mysql
#删除服务
[root@hadoo hadoop001 p39 mysql]# chkconfig –del mysql
#添加服务
[root@ hadoop001 mysql]# chkconfig –add mysql
[root@ hadoop001 mysql]# chkconfig –level 345 mysql on
[root@ hadoop001 mysql]# vi /etc/rc.local
#!/bin/sh

# This script will be executed *after all the other init scripts.
*# You can put your own initialization stuff in here if you don’t
# want to do the full Sys V style init stuff.**
